For many years, this internationally famous facility has taught photographic expertise in practical seminars and training courses. It meets the needs of keen photographers, both beginners and advanced students, for special training in demanding areas of 35 mm photography, projection, and enlargement. Up-to-date, well-equipped seminar rooms are available at our Solms headquarters and at the nearby "Gut Altenberg" for these courses, which are held by experienced instructors, the content of which ranges from general photography to specialised fields of interest. [. . . ] The irregular structure of the metering spot in no way affects the meter reading. The lens f-stop and shutter speed for correct exposure are indicated by the appearance of the light balance ( ) in the viewfinder: the exposure is correct when only the round LED in the middle comes on. Exposure metering The LEICA M6 TTL meters for exposure under ambient light through the lens at the working aperture. The reading is selective, by light reflected from a bright metering field onto a photo diode (arrow). This diode is located behind a collecting lens to the left of and above the shutter. 13% of the negatives size) is situated in the centre of the first shutter curtain. Switching on the exposure meter The exposure meter is switched on by light pressure on the shutter release button (7), providing that the shutter is cocked and the shutter speed dial is not set to "B" or "OFF". When one of the two triangular LEDs or the central round LED comes on, the exposure meter is ready for operation. 24 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals If finger pressure is released without the shutter being depressed, the exposure meter remains switched on for approx. When the shutter is activated, the meter switches off and the LEDs in the viewfinder go out. When the shutter is not cocked, or the shutter speed dial is set to "B" or "OFF", the exposure meter remains switched off. at the threshold of the light metering range, the LEDs may take approx. If the luminance levels fall below the working range of the exposure meter, the left-hand triangular LED flashes. Then: 1. Turn the shutter speed dial and/or the aperture ring on the lens in the direction indicated by the flashing LED until only the round LED comes on. In addition to the direction of rotation of both shutter speed dial and lens aperture ring required for correct exposure, the three LEDs of the light balance also indicate over-, underand correct exposure as follows: Underexposure by at least one f-stop; turn lens aperture ring clockwise. Correct exposure Overexposure by half an f/stop; turn lens aperture ring anticlockwise. Overexposure by at least one stop; turn lens aperture ring anticlockwise. Setting shutter speed/lens aperture combinations for correct exposure For correct exposure metering, the shutter must be cocked and the shutter speed dial must be set at a marked speed. 25 Not For Resale ­ Free Download at http://www. joe-chan. com/manuals Meter sensitivity The light metering range begins at 0. 03 cd/m . The working range at ISO 100/21° extends from -2 to 20 EV (exposure value), i. e. from 4 s (shutter speed dial position "B") at f/1 to 1/1000s at f/32 (see also diagram on page 29). 2 General information on exposure metering Most scenes contain an even distribution of bright and dark subject details and reflect an average of 18% of the light falling on them. This value of 18% corresponds to an average grey tone to which exposure meters are calibrated. Very bright subjects, such as snowladen winter scenes, sandy beaches, whitewashed walls or a white wedding gown, reflect more light toward the exposure meter, tending to result in underexposure. Predominantly dark subjects such as a black steam locomotive, dark grey slate roofs, and navy-blue uniforms reflect much less light, and meters tend to overexpose. To achieve correct exposures in these cases, the measured values must be corrected, unless exposure is measured selectively by inclusion of only a portion containing a representative sampling of dark and light subject details. You would for example meter on the bride's face and not on her white gown. A landscape shot with a wideangle lens should be metered with the LEICA M6 TTL pointing downward to exclude the bright sky. [. . . ] Clickstop settings, can be read from above: OFF, B, 1 to 1/1 000s and F (=1/50 s, flash sync speed, i. e. fastest shutter speed for flash operation); intermediate settings not possible. Setting the correct shutter/aperture combination: Switch on exposure meter. Turn shutter speed dial and/or aperture ring until the central round LED (for precise exposure) or the central round LED and one of the triangular LEDs (for exposure with ± 2EV) in the viewfinder come on; only one of the triangular LEDs flashing indicates over- or underexposure together with the required direction of rotation of the aperture ring and shutter speed dial.
